1. The use of LED glue: waterproof, heat-killing, anti-oxidation and other purposes, mainly to protect led display.

2, LED glue classification: According to the usage can be divided into the production of LED epoxy resin and LED display module used in the filling glue (the following LED glue refers to the LED display module filling glue).

According to product quality and use environment and other factors, it is divided into: special glue, high-grade glue, low-grade glue and so on.

3, LED glue and other times:

At present, LED glue on the market has three levels ：

Special glue: Special glue mainly refers to the LED glue that requires high requirements for LED display environment, such as cold (North) glue, high temperature (high temperature environment) glue, corrosion resistance (acid and alkali environment) glue and other special requirements and environment. LED display glue used.

High-grade glue: special glue for full-color LED display, generally black glue, with high heat resistance, cold resistance and waterproof effect.

Low-grade glue: the general protection effect is very poor.

4. How to judge the quality of glue:

Professional testing: From a professional perspective, special equipment is needed to analyze the composition of the LED glue, as well as the ratio between the components and the actual data obtained through actual environmental tests.

Simple identification: When filling the glue, you can check the main data such as leveling and curing time according to the regular ratio. After curing, you can check the quality of the glue according to the color condition and the elasticity of the rubber. The finished LED module can be used to remove the screws and the cover plate to make a simple judgment (good general soft and moderate, good elasticity).
